Hi,
Thank you for contacting the Mobile Ads SDK Support team.
Yes, according to Article 7(1) of GDPR, data controllers must keep a record of user consent. While consent is stored locally on the user's device (e.g., in TCF string in SharedPreferences for Android and NSUserDefaults for iOS), it's also advisable to store this consent information securely on a server. This allows data controllers to maintain a central record of user consent and facilitates compliance with GDPR requirements. Access to individual user consent information should be controlled and managed securely to ensure data protection compliance.
When you enable consent mode, Google measurement products ensure that a visitor’s consent mode state is preserved across the pages they visit. If consent is denied, tags that fire do not store cookies, instead they communicate a minimum of information about user activity. Consent state and user activity are then communicated by sending the following types of cookieless pings, or signals, to the Google server
